A major controversy
The debate over our origins looks set to run and run. Most DNA evidence supports the 'Out-of-Africa' theory. But some appears to support the 'multiregional' theory: for example, one study suggests that people living in Asia and Africa both originated from common ancestors living in Africa as long as 800,000 years ago. The most recent theories offer a compromise: maybe 'modern' human replaced 'ancient' humans in some parts of the world, including Europe, but interbred with them in others, particularly Asia.
